DS1233AZ-10

Supervisors Overview

The DS1233AZ-10 is a voltage supervisory circuit from the EconoReset series by Analog Devices / Maxim Integrated. It features a 3.3 V threshold voltage and operates within a supply voltage range of 1.2 V to 5.5 V. The device provides power failure detection with an active low, open drain output type. It includes manual reset functionality and has a reset delay time of 450 ms. The component supports one monitored input and draws a working supply current of 50 uA. It is housed in an SOT-223-3 package for surface mount installation and functions across a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Provides precise power failure detection with internal voltage reference
• Includes manual reset capability with internal button debounce
• Maintains reset state during undervoltage conditions

Supervisors Applications

• Microprocessor system power monitoring
• Embedded controller reset control
• Portable electronic device power supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as this part may be discontinued or restricted in certain regions. Confirm RoHS compliance status and specific suffix variations against official datasheets before procurement. Ensure storage and handling procedures align with manufacturer guidelines for sensitive semiconductor components to maintain reliability.

Supervisors Selection Notes

Select this model when a 3.3 V threshold is required for single-input voltage supervision. Consider the SOT-223-3 package for surface mount applications requiring compact footprints. Evaluate the 450 ms reset delay against system timing requirements. Compare against other EconoReset variants if different thresholds or manual reset features are needed.

Supervisors Part Context

The DS1233AZ-10 belongs to the DS1233 family of supervisory circuits designed for cost-effective power management solutions. This series integrates voltage sensing and reset generation into a single component, reducing discrete component count. The AZ suffix typically indicates specific manufacturing lot or packaging details within the broader product line managed by Analog Devices / Maxim Integrated.
